Ask YC: Google registered domains unreachable right now?

I have two domains registered via google apps (registrar is enom). I can't reach them anymore. Is anyone else having the same problem?

Here's some analysis output I got via http://intodns.com

DNS servers responded

ERROR: One or more of your nameservers did not respond: The ones that did not responded are: 98.124.192.1 98.124.193.1 216.52.184.248 70.42.37.7 69.64.145.225

No SOA, MX, A records. Just dead. How can all these name servers fail at the same time?
